I've got the same headlights too. I'm currently working on a DIY. I'm trying to source out connectors and pigtails to perform a OEM looking finish to this mod.

Keep you all posted

After a lot of digging I've figured out how to wire the JDM 02-03 CTR HID headlights. USDM 02-03 EP3 headlights have a single power source wire and two grounds (HI and LOW). What you do is:

1 - Add a second source wire by splicing into the original source wire (L headlight - red/yel wire, R headlight - red wire).
2- One source wire goes to the igniter (low beam)
3- Other source wire goes to the HI beam solenoid.
4- The igniters get grounded on the front bumper beam (G201 AND G301)
5- HI beam solenoids ground through the L headlight connector red/blue wire, and R headlight connector red/blue wire.

Voila!
Tested and true

If you're converting to HID than you should be using a subharness to power everything. The OEM harness in the car isn't adequate to power the new ballast installed.

With all due respect, I would like you to explain in detail how you came up with that comment. Or are you simply going by what others are telling you? The "ballast", aka igniter for the Honda people, requires a 12V source. Which we have. The igniter's job is to turn this 12V into 12'000 or more volts in order to initially create the "arc" in the bulb. Once the arc is acheived the igniter provides the constant power needed to keep the arc.

After reviewing a large amount of photos from Japanese and British counterparts, I've confirmed that the wires leading into the JDM igniters (aka ballasts) are all 16 gauge copper wires. Identical in size as those found with the sidemarker wires etc. Also, after extensive calculations of current capabilities, the OEM wire harness' can handle the HID's well.

To further prove this I also mocked up the wiring on a bench and physically tested the circuits for current draws. The systems uses a little less than 9 amps with both headlights on and using a couple of inches of 16 gauge copper wire. 16 gauge copper wire is spec'd to be able to handle 20A or less of current. So we're good.

Therefore, I don't understand what everybody is worried about. Am I missing something?

After spending $225 on new headlights and close to $500 on an all OEM HID setup for my car, what's another $20 bucks for a new subharness with easy to replace fuses that I know won't have any problems.

Also, If you're installing '04-'05 headlights which have two separate bults for high and low beam, how do you intend to make that work with your '02-'03 EP3 that uses a single bulb? The easiest method is to use a subharness.

its good rule of thumb to go ahead and spend whatever few dollars to get the harness either already made from a site or makin it yourself... you'll wind up frying your stock headlight harness over time... its acts almost like a surge protector in case there's a fluctuation in it...

everything you wanna learn about hid's can be done from ocelaris's threads... here's one to get you started...

Many aftermarket companies are trying to scare people into buying the HID subharnesses. They are not required in our case. I've done countless amount of hours of research, math and field testing to prove this. I too do not want to set my car on fire. I want to be damn sure that everything is fine before I do this. Like I've stated before, a fellow EP3'er in the UK was kind enough to forward me pictures of the his JDM HID headlight harness wires leading into the Honda igniter. They are the same size wire as the side marker lights. The math even proves the theory.

If you want to waste money, by all means..... go nuts. I'll keep those dollars and spend them elsewhere.

ive got HID's on the JDM CTR's and am running on the EP stock harness with no problems. I have an 04 EP.
04-05 EP3 headlight wiring diagrams are almost similar to the JDM EP3-R HID's. Both use four wires. Two to power the low beam (aka igniter). And the other two to power the hi/lo solenoid (02-03 EP3-R's) or high beams (04-05 EP3's).

There's a little more work required for the 02-03 EP3's, but not a big deal.

Here's a wiring schematic that I've come up with

Is there a diagram on this installation, it would help a lots. I am little lost on #4 where you say "The igniters get grounded on the front bumper beam (G201 AND G301)" so can i just ground it anywhere on the chassis.

Seems so. I think he is talking about the front rebar.

Yeah. If you remove the front bumper you'll see two cluster of grounds on each side of the frame where the rebar bolts up to. Use those.
